docs: def updateLicenseManager(self, licenseManagerInfo):
          """
          ArcGIS License Server Administrator works with your portal and
          enforces licenses for ArcGIS Pro. This operation allows you to
          change the license server connection information for your portal.
          When you import entitlements into portal using the Import
          Entitlements operation, a license server is automatically configured
          for you. If your license server changes after the entitlements have
          been imported, you only need to change the license server
          connection information.
          You can register a backup license manager for high availability of
          your licensing portal. When configuring a backup license manager,
          you need to make sure that the backup license manager has been
          authorized with the same organizational entitlements. After
          configuring the backup license manager, Portal for ArcGIS is
          restarted automatically. When the restart completes, the portal is
          configured with the backup license server you specified.
  
          Parameters:
             licenseManagerInfo - The JSON representation of the license
               server connection information.
